DAY TRIPPER
by the Beatles falls in category 14–mixed fast. Creative title–not.
So said, it is my hypothesis that when a song has a mean speed of over
129 beats per minute, the theme goes outside a predictable victorious
mood into a mixed stae. That mixed state may be of any emotion at all.
The mean speed of DAY TRIPPER is very Rolling Stones–I think 1/2 of
the Stones songs clock in at this speed–between 132 and 142 BPM.

This song was written and recorded whe all the Beatles were high from marijuana. Then again, same is true for every Beatles song ever recordedd. Source: The Beatles. (IN THEIR *OWN* WORDS ONLY).
